For PORT, use the number of the IO-Link port, not
the number of the channel.
▶ Generate a rising edge at REQ to start the data transmis-
sion.
Processing of the function block takes several PLC cycles.
During processing, the BUSY output is on 1.
After successful processing, the BUSY output switches to 0.
The DONE_VALID output switches to 1. During read access,
the data read is displayed in the data block.
6.11 I&M functions
Reading and writing can be realised with the functional
blocks RDREC (SFB52) and WRREC (SFB53) in STEP 7.
